Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT GLF-F Mechanical Seal	A high - performance mechanical seal designed for a wide range of industrial applications, ensuring reliable sealing under various working conditions.
Model	QT GLF-F	This model is engineered with advanced technology to provide excellent sealing performance and durability.
Materials
- Rotating Ring	Tungsten Carbide	Tungsten carbide offers high hardness and wear resistance, enabling the rotating ring to endure harsh operating environments and high - speed rotations, thus extending the seal's service life.
- Stationary Ring	Silicon Carbide (SiC)	Silicon carbide is chosen for its superior corrosion resistance and smooth surface finish, which are essential for maintaining effective sealing and reducing friction.
- O - Ring	Fluoroelastomer (FKM)	The FKM O - ring provides a tight seal and is resistant to a broad spectrum of chemicals and temperature variations, ensuring consistent performance.
Size Specifications
Shaft Diameter Range	25 - 60 mm	Suitable for installation on shafts with diameters within this range, making it applicable to a variety of pump models and sizes.
Seal Chamber Inner Diameter	35 - 70 mm	Designed to fit into seal chambers with inner diameters in this range, ensuring proper alignment and installation for optimal performance.
Seal Width	10 mm	The 10 - mm width is optimized to strike a balance between effective sealing and minimizing energy consumption due to friction.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operating conditions, the seal can withstand a maximum pressure of 2.0 MPa, effectively preventing the leakage of the pumped medium.
Working Temperature	-25ºC - 180ºC	Capable of operating efficiently within this wide temperature range, making it suitable for applications in both extremely cold and high - temperature environments.
Linear Velocity	Maximum 12 m/s	The seal is able to handle a maximum linear velocity of 12 m/s, ensuring stable performance even at high rotational speeds of the pump.
Applicable Media
- Water - based Fluids	Ideal for use with clean water, process water, and various aqueous solutions with a pH range of 2 - 13.
- Oil - based Fluids	Compatible with mineral oils, synthetic lubricants, and most hydraulic oils.
- Chemical Fluids	Resistant to many common acids, alkalis, and solvents, but specific compatibility should be verified based on the actual chemical composition.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a precise installation procedure to ensure correct positioning and tight sealing.
Installation Torque	18 - 22 N·m	During installation, a torque within this range should be applied to secure the seal properly without causing damage to the components.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance every 4000 operating hours is recommended. This includes inspecting the seal for signs of wear, leakage, and any damage to the components.
Storage Conditions	Store in a dry, cool place with a temperature range of 5ºC - 25ºC. Keep away from direct sunlight, moisture, and corrosive substances.	Proper storage conditions help preserve the quality and integrity of the seal, preventing premature aging and degradation.
Quality and Certification
Service Life	Approximately 2 - 3.5 years under normal operating conditions	With proper operation and regular maintenance, the QT GLF - F seal can provide reliable service for 2 to 3.5 years.
Leakage Rate	≤0.12 mL/h	Engineered to have a low leakage rate, ensuring minimal loss of the pumped medium and maintaining system efficiency.
Certification Standards	ISO 9001, API 682 (if applicable)	Meets the requirements of ISO 9001 quality management system standards and may comply with API 682 for specific industrial applications.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 10 - 60 Hz and an amplitude of 0.6 mm.	Designed to maintain its sealing performance in environments with moderate to high levels of vibration.
Self - lubricating Property	The seal faces are coated with a self - lubricating material, reducing friction and wear during operation.	This self - lubricating feature enhances the seal's durability and reduces the need for additional lubrication, improving overall efficiency.
